[Guidelines for clinical application of micronutrients in Chinese adult patients (2024 edition)].

Micronutrients, including trace elements and vitamins, are essential nutrients in human metabolism. The majority of patients who need nutritional therapy have different levels of micronutrient deficiency for various reasons, which can lead to disease progression and affect clinical outcomes. In order to further standardize the application of micronutrients in medical nutrition therapy, nearly 100 experts in related fields were organized by the Chinese Society of Parenteral and Enteral Nutrition (CSPEN) to elaborate on the role and dosage of micronutrients based on the existing evidence-based medical evidence in common clinical conditions such as severe illness, surgery, burns, inflammatory bowel disease, short bowel disease, malignant tumors, chronic liver and kidney disease, elderly comorbidity, weight loss and chronic infection. Finally, 13 questions and 30 recommendations were put forward to provide reference for clinical standard application of parenteral and enteral nutrition in adult patients.
